3. The Californian district includes a marked northern element, the principal constituents of which are identical with types occurring in the corresponding district of the Atlantic, viz. the North American, as exemplified by Discoboli, Anarrhichas, Centronotus, Cottus, Hippoglossus, Clupea (harengus), etc. But it possesses also, in the greatest degree of development, some types almost peculiar to itself, as the Heterolepidina, some remarkable Cottoid and Blennioid genera, and more especially the Embiotocoids—viviparous Pharyngognaths—which replace the Labroids of the other hemisphere. Gadoids are much less numerous than in the North American district. The southern forms are but little known, but it may be anticipated that, owing to the partial identity of the Faunæ of the two coasts of the Isthmus of Panama, a fair proportion of West Indian forms will be found to have entered this district from the south. The following are the principal genera:—
Chimœra, Galeus, Mustelus, Triacis, Cestracion, Rhina, Raja.
